modul 6

1. What are Network Operating Systems designed to do? *share resources across a network with multiple users remotely control other computers on the network access and control the local hard disk run stand-alone computers that are not LAN capable

2. A user account on a server enables the server to do which of the following? automatically download appropriate applications and print queues to that user *authenticate that user and allocate those resources the user is allowed to access assign a specific IP and MAC address to the user's workstation assign the user to a specific domain and user group

3. What are two benefits of having more than one processor in a system? support for remote locations and automatic job queuing *faster speeds and increased work capacity reduced need for IP addresses and decreased boot time reduced need for IP addresses and increased manageability

4. How is redundancy built into a server system? *by including additional hardware components that can take over if other components fail by including a tape back-up system to preserve data by adding redundancy software to the system by keeping duplicates of all data

5. What are two important features provided by security on a NOS? *authentication and encryption reliable performance and account management virus protection and prevention from spamming processor balance and sustained work load

7. In a Windows NT environment, what is the meaning of the term domain? a dedicated server containing the database of all IP and MAC addresses on the network a group of computers located in a specific physical or geographic region the OU that contains all user accounts *groups of computers, users, and resources that form an administrative boundary

9. In Windows 2000, administrative tasks are accomplished using the Microsoft Management Console. Which type of module does this tool require for specific administrative functions? plug-in add-on *snap-in clip-on

10. Windows 2000 Professional supports plug-and-play technology. What is one of the major advantages of this technology? An administrator can add devices from any manufacturer to the system and they will work. Devices no longer need software drivers to interact with the system. Components will interact with the system if plugged in prior to system boot. *An administrator or user can easily add components to the system without manual configuration.

14. In Windows 2000 Server, what is the function of symmetric multiprocessing? *It allows multiple processors to work together to share the workload in a computer. It provides for redundancy of data over multiple processors to prevent data loss. It assures that each processor in the server works on the same projects simultaneously. It monitors the processors for errors, performance levels, and queued jobs to ensure quality.

16. Which of the following is open source? all versions of UNIX Windows 2000 all versions of NetWare *Linux

17. Which of the following criteria must software meet in order to display the Open Source Initiative trademark? It must be easily altered and adapted to all major operating systems and source code must be limited. It must be compatible with third party add-ons and use standard source code. It must be provided in multiple languages and cost must be minimal. *It must be freely distributed without restriction and the source code must be available.
